If the world's leaders really cared about climate change, there's one easy way to reduce emissions, writes John Weeks - drop the obsession with increasing trade, and all the pollution that goes with it. A world based on local production, consumption and finance will be a better one for people and the environment.more...

We must accept the reality that human beings, nature and cosmos are interconnected in a vast circular system, writes Jane Cull. To sustain ourselves on this planet, we must sustain the web of life of which we are part, and construct another kind of world that based on that understanding.more...

Nuclear power exists for one reason only, writes Ralph Nader - government support. Without the taxpayer subsidies, accident liability waivers and exploited consumers, nuclear power wouldn't exist. And even with all the above, it can barely hold on. It's time to end the nuclear boondoggle for once and for all.more...

Hunter Lovins is on a mission, writes Sophie Morlin-Yron: to put the transformational technologies we already have to work for the benefit of people and business - and to re-create the economy so it's no longer a machine for polluting the planet and devouring natural resources, but a mechanism for building and sustaining natural and human capital.more...

Beneath half a mile of ice scientists have uncovered the first hard evidence of a life in a subglacial lake, writes Helen Thompson. And not just life, but a complex ecosystem comprising thousands of microbial species. Could Jupiter's frozen moon Europa be hiding lakes like this?more...

As Brazil prepares for elections next month, conserving its remaining Atlantic Forest is a hot issue, writes Cristina Banks-Leite. Ecologists want to preserve more native habitat, while farmers want to expand their acreage. But there is one solution that ought to please everyone.more...

After rabbits, foxes, brambles and the cane toad, you would have thought Australia would have had enough of invasive exotic species, writes Jane Wright. Wrong!

The green dream of being a small farmer producing high quality, organic food for local people has ended up being anything but for Alicia Miller. The problem is money - there's never enough of it. But she's not alone. All over the world, life is a financial struggle for small, ethical cultivators, and constant source of stress.more...

Even if you love Himalayan balsam, it has surely become too much of a good thing as it takes over Britain's wetlands and riverbanks. But now it's facing a major setback - the deliberate introduction of a parasitic rust fungus from its native range in the mountains of Asia.more...

Is the species that dwells peacefully within its habitat with respect for the rights of other species the one that is inferior? Or is it the species that wages a holy war against its habitat, destroying all species that irritate it? Paul Watson questions man's monopoly on advanced brain power, and finds a planet suffused with a far deeper intelligence than our own.more...

Mussels, crabs, hornets and ... racoons? Future invasive species are not what you might expect, write Jodey Peyton & Helen Roy. In particular, we have to beware of 'ecosystem engineers' that can transform the environment they inhabit, creating ecological havoc for other species.more...

A second canal joining the Pacific and Atlantic oceans is planned for Nicaragua, writes Nathan Wood. But the gigantic project is raising growing fears due to a grossly unfair contract, glaring failures of process, close links to the Chinese government, and its enormous - but uncosted - ecological impacts.more...

How do we spur more microgrids powered by renewable energy? Deregulate, writes Bill Watkins, ending the monopolies enjoyed by centralized energy companies. The alternative is to keep consumers and micro-generators stuck with the energy equivalent of the 'Princess' phone.more...

India's economy is hindered by the lack of sustainable and reliable electricity, writes Michael Jacob. But the new government has a plan to bring 24/7 power to every citizen, based on grid renewal, subsidy cuts, and a big rollout of ever-cheaper solar power generation.more...

Plastic waste, often burning, is a constant companion in Gambia, a poor country where few enjoy formal rubbish collection, writes Louise Hunt.
